Make [SD]rotm{,g} more idiomatic Go
...
We now have an int Flags type that indicates the status of the H matrix
and the [SD]RotmParams struct is returned as a concrete type since it is
not intended to be mutated by the rotm routine.
This also picked up a non-allocation bug in goblas.Drotmg.

Add test for Norm
...
Norm(±2) is, not surprisingly, difficult to pin down. The expected
values here agree with numpy well for Norm(2), less will with MATLAB
and the expectation for Norm(-2) is a fair amount (FWIW at this
magnitude) away from the numpy and MATLAB values which agree quite
well with each other.
